IMPORTANT!

READ INSTALLATION INSTRUCTIONS FIRST

Thank you for your confidence in our product. To obtain the best results from your investment, please read these instructions and acquaint yourself with your purchase before installing your new thermostat. Then follow the installation procedures, one step at a time. This will save you time and minimize the chance of damaging the thermostat and the systems it controls. These instructions may contain information beyond that required for your particular installation. Please save for future reference.

FEATURES

- The TX1500 can be used with most 24 volt gas, oil or electric heating and air conditioning systems, single-stage heat pumps or gas millivolt heating systems. It cannot be used with 120 volt heating systems or multistage heat pumps. Ask your dealer for other LUX thermostats to control those systems.

- The TX1500 is programmable. There are four programming periods per day. Each period can be programmed se

- Easy to use Lux Speed Dial®

- You can use the built-in time/temperature programs, or alter them to suit your schedule. The TX1500 provides separate programming for weekdays, Saturday, and Sunday — for both heating and cooling. You can override the programmed temperatures for as little as one programming period or for an entire vacation.

- In cool weather, when the system switch is set to HEAT, the TX1500 will maintain cooler "set back" room temperatures to save energy. It will then change to warmer "comfort" settings — all automatically, at specified times during the day.

- In warm weather, when the system switch is set to COOL, the TX1500 will maintain warmer "set back" room temperatures to save energy. It will then change to cooler "comfort" settings - all automatically, at specified times during the day.

- A large liquid crystal display shows time, day of the week, and room and set temperatures. It will remind you when the filter should be changed in your blower.

- Temperature swing adjustment lets you fine-tune your system for maximum comfort and economy.

- 5/2 Minute Selectable Minimum Run/Off Time for Short Cycle/Compressor Protection

- Two Energizer® or DURACELL® "AA" alkaline batteries (not included) are used to retain your time and temperature program and to light the display.

C A U T I O N

• Your thermostat is a precision instrument. Please handle it with care.
• Turn off electricity to the appliance before installing or servicing thermostat or any part of the system. Do not turn electricity back on until work is completed.
• Do not short (jumper) across electric terminals at control on furnace or air conditioner to test the system. This will damage the thermostat and void your warranty.
• All wiring must conform to local codes and ordinances.
• This thermostat is designed for use with 24 volt and millivolt systems. The thermostat should be limited to a maximum of 1.0 amps; higher amperage may cause damage to the thermostat. If you are in doubt, call your utility company.

INSTALLATION

Please read all instructions carefully before beginning installation.

TOOLS REQUIRED

1 Phillips screwdriver (small)

Drill with 3/16-in. (4.8mm) bit

THERMOSTAT LOCATION

On replacement installations, mount the new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new installations, follow the guidelines listed below.

1. Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, and in a room that is used often.
2. Do not install it where there are unusual heating conditions, such as: in direct sunlight; near a lamp, radio, television, radiator, register, or fireplace; near hot water pipes in a wall; near a stove on the other side of a wall.
3. Do not locate in unusual cooling conditions, such as: on a wall separating an unheated room; or in a draft from a stairwell, door, or window.
4. Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life.
5. Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open door.
6. Do not install the unit until all construction work and painting has been completed.
7. This thermostat does not require leveling.

REMOVING THE OLD THERMOSTAT

Switch electricity to the furnace and air conditioner OFF; then proceed with the following steps.

1. Remove cover from old thermostat. Most are snap-on types and simply pull off. Some have locking screws on the side. These must be loosened.

2. Note the letters printed near the terminals. Attach labels (enclosed) to each wire for identification. Remove and label wires one at a time. Make sure the wires do not fall back inside the wall.

3. Loosen all screws on the old thermostat and remove it from the wall.

MOUNTING THE TX1500 ON THE WALL

1. Strip insulation 3/8 in. (9.5mm) from wire ends and clean off any corrosion.

1. Fill wall opening with non-combustible insulation to prevent drafts from affecting the thermostat.

2. Press up on the button on bottom of thermostat and swing the body away from the base and up to remove the body from the base.

C A U T I O N

Be careful not to drop the body or disturb electronic parts. Leave the cover closed while the body is being removed from the base.

CAUTION

Read instructions carefully before removing any wiring from existing thermostat. Wires must be labeled before they are removed. When removing wires from their terminals, ignore the color of the wires since these may not comply with the standard.

Base Terminals G Y W RH B O RC Latch Button

NOTE
If you are mounting the base to a soft material like plasterboard or if you are using the old mounting holes, the screws may not hold. Drill a 3/16-in. (4.8mm) hole at each screw location, and insert the plastic anchors provided. Then mount the base as described below.

ATTACHING WIRES

4. Hold the base against the wall, with the wires coming through wherever it is convenient for wiring. Route the wires to below the terminal block. Position the base for best appearance (to hide any marks from an old thermostat). Attach the base to the wall with the two screws provided.

C A U T I O N

Do not allow wires to touch each other or parts on thermostat. Wires must be trapped between black spacer and brass terminal. Also, be sure to tighten securely all 7 electrical terminal screws.
